I used to tell people that I was an atheist, and my wife told me I was more of a "fundamentalist atheist" because I wanted everyone else to be too.

Now I call myself a "Reformed Fundamentalist Atheist" because it captures that I don't care anymore (reformed), and it sounds enough like a real religion that people seem to accept it as one.

In the spirit of many of the good things on the internet, the Reformed Fundamentalist Atheist church (RFA) is of course an open source religion, under the MIT license :)
